Deloitte Senior Project Controller interview questions

The process is very friendly and straightforward. I was referred to Deloitte by a personal friend who also works at Deloitte, contacted by a recruiter for the position, and then we set up an initial phone interview within a couple days of that first e-mail exchange. After that phone interview, where we just went over my resume and basically it's applicability to the job, I was told I would be recommended for a second "technical" phone interview with someone from the group at a level higher than the one I was applying for. I had that phone interview a couple days later and we also mostly just discussed my resume and some soft-skills type questions about time-management and delegation, for example. Both phone calls were very laid back and low stress. A few days after that (could've been even a week or so), I heard back from my original recruiter (who did the first phone interview) and she said I was going to be invited into the office for in-office interviews. It took a while to get the official invitation from another HR representative (1-2 weeks) and then I was scheduled to come into the office about 2 weeks after that. I had three in-office interviews: 1) a fit interview (same as the phone interviews, basically), 2) a 'financial' interview (where I also talked mostly about my resume and past experiences), and 3) a case interview. I will say that I read a text book on case interviews cover-to-cover, practiced at least 50 different cases, and put in a total of close to 30 hours of studying for this case interview - and it was 30 hours too much. I didn't really get a case in the true sense of the word but was given a very general scenario and asked how I would (or have in the past) handle it. Everyone I talked to was very friendly, approachable, and I felt completely comfortable. I heard back within one week with an email saying that the team was preparing an offer and I got the actual offer another week later (so probably two weeks after my interviews).
